This data set contains Jupiter-encounter, particle count-rate data written on a magnetic tape by a UNIVAC 418 computer. The tape is composed of a number of 695-word (18-bit words) records. Each record contains spin-averaged rates for each channel and 23 frame-by-frame rates for each channel together with the corresponding spacecraft roll angles. The angular resolution is about 7 deg, and two records are required for complete angular coverage. Each record contains time and spacecraft-trajectory information and the spacecraft position and orientation in Jovian system-III coordinates. A malfunction of the standby data processor caused an appreciable (up to 30%) error in two of the seven nonredundant count-rate channels for a period of about 3 days following periapsis. Further details are provided in documentation accompanying the data set.
